APPARATUS FOR PREVENTING FREEZING OF WATER-PIPES.

SPECIFICATION forming part of Letters Patent No. 682,497, datedSeptember 10, 1901.

Application filed April 5', 1901- S'erlal No. 54,535. (No model.)

To all whom it may concern.-

Be it known that I, J ULIUS RiiHLINe, a citizen of Gera, residing atGer-a, Reuss Younger Line, Germany, have invented certain new and usefulImprovements in Oontrivances to Prevent the Freezing in ofWater-Conduits; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to a device for preventing the freezing in ofwater pipes in which the water of the pipes is forced to pass firstthrough a coil of pipe in a heating apparatus before it reaches thefloors of a dwelling or other building. There is also above the heatingserpentine a reservoir which is fed at the same time with the waterheated in the coil, from which reservoir by a separate pipe the vaporsdeveloping therein are conducted, by means of branch pipes, to closetsor similar apartments for the purpose of warming them.

In the accompanying drawings, Figures 1 and 2 represent, respectively,vertical and horizontal sections through a device constructed inaccordance with my invention, the latter on line 2 2 of the former.

The main conducting-pipe b, with a stopvalve a, is provided at thebranches 0 d, having valves 0 and d, which are connected by thecouplingsfand fwith the heating-coil g. The reservoir A above the'coilgand provided with a safety-valve h is connected by a pipe 1' with thecoil 9 and has a glass gage 7.0. For cutting off the pipe 2' from theserpentine g and the conduit 1) no valve or cock is shown in thedrawings. The pipe 2' serves as an out-. let for the vapors developingin the reservoir A and may be connected by branch pipes (not shown)leading to the apartments to be heated.

on is the chimney.

To make use of this device it is necessar der possible an easy emptyingwhen desired. The water may be heated with any suitable fuel. reservoirA, thereby causing the vaporization of the water contained therein andalready heated in coil g, so that the vapors are led by conduit Z to theapartments to be heated.

While not using this device the valves (3' and d are closed and valve onopen ed,whereby the water passes through pipe I) unheated. If for anyreason it is desirable to place the device in another room, thecouplings f and f may be loosened and connection to the main pipe madein another place.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-- 1. In adevice of the character described, the combination with a heater and asuperposed water-tank, of a main water-pipe, a coil of pipe in thefire-box of the heater, valved connections, between the ends of the coiland the main pipe, a valve in the main pipe between said connections, abranch pipe leading from the main pipe, beyond the coil connections,into the water-tank, and a pipe leading from the top of the tanksubstantially as and for the purposes set forth.

2. In a device of the character described, the combination with a heaterand a superposed water-tank surrounding the chimney of the heater, of amain water-pipe, a coil of pipe in the fire-box of the heater, valvedconnections having interposed couplings between the ends of the coil andthe main pipe, a valve in the main pipe between said connections, abranch pipe leading from the main pipe, be yond the coil connections,into the watertank delivering below the water-level thereof, and a pipeleading from the top of the tank substantially as and for the purposesset forth.

In testimony whereof I affix my signature in presence of two witnesses.
